垂直界面裂纹断裂力学问题的实验研究

AN EXPERIMENTAL ANALYSIS OF FRACTURE MECHANICS FOR CRACK TIP NORMAL TO INTERFACIAL

  • 摘要: 用实验方法研究了具有垂直界面方向裂纹的界面断裂力学问题.根据实验结果对裂尖区域的奇异性性质、角位移分布、应力强度因子等进行了分析,并将实验结果与理论结果进行了比较和讨论

     

    Abstract: The problems of an interfacial crack with the crack tip normal to interface are investigated by experiment. High-resolution moire interferometry methods are employed to get displacement fields surrounding cracks. The order of singularity of displacement faction of angular displacement and stress intensity factor are determined from experimental results and it also be compared and discussed with some theoretical results.
